Lewis dot structure in the case of ammonia is a representation of the valence electrons surrounding the N atom.
The dot dot structure for ammonia displays that the N atom joins one pair of e- with each of the three hydrogen atoms, resulting in a complete of a trio shared pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal form because of the distribution of the outer electrons according to its Electron pair Beverage cup
structure.
In the Lewis dotpoint representation of ammonia, the N atom is enclosed by three spots, each representing a pair of shared electrons with a H atom.
